apropos

- locate commands by keyword lookup

Synopsis

aproposkeyword...

Description

The apropos utility displays the man page name, section number, and a
short description for each man page whose NAME line contains keyword. This information
is contained in the /usr/share/man/windex database created by catman(1M). If catman(1M) was not
run, or was run with the -n option, apropos fails. Each word
is considered separately and the case of letters is ignored. Words which
are part of other words are considered; for example, when looking for `compile',
apropos finds all instances of `compiler' also.
